Hey Indy, 9mm, 357 and 380 brushes are all the same. As far as cleaning from the muzzle, I wouldn't do for the reasons you already gave. Really, there is no reason to do that as easy as it is to field strip the LCP....Indy Man said:Hello all, I had bought a universal pistol cleaning kit from wally world that stated on package it contained a 9mm brass brush so I thought ok this will work in the lcp but no 9mm it was a 357 brush so my question is will this work in cleaning the lcp untill i locate a 380 brush? Also do any of you clean your pistol from the muzzle end? and would this be ok to do as I have not tried in fear of scratching the muzzle.
